当前，随着通信技术的快速发展，越来越多的公司和个人通过网络召开多用户会议。现有的多用户会议系统多是基于视频的。视频会议系统通常包括视频会议终端、视频会议服务器(Multipoint Control Unit，MCU)、网络管理系统和传输网络等部分组成。视频会议终端和MCU将会议现场的图像、视频、音频等信息进行编码打包并发送；终端对收到的数据包解码还原为图像、视频、音频等。
现有的视频会议系统所传输的数据是基于图像或视频的，传输的数据量很大，对网络处理速度和网络流量的要求较高。另外，会议内容的保存需要的存储空间也较大，这使得视频会议系统的成本较高。并且，由于当前有越来越多的场景为多个公司或多人在同一个场地办公，这就有可能会出现多个公司或多人使用或租用同一个多用户会议系统来开展会议。此时，如何保证会议产生的数据的安全性成为一个重要问题。

图1示出了根据本发明实施例的多用户会议系统100的示意性框图。如图1所示，该多用户会议系统100包括红外设备110和云服务器120，其中，该红外设备110不具有显示屏，且使用时置于书写承载介质上，该红外设备110、该云服务器120和多个用户使用的终端创建并参与会议，该红外设备110包括网络设置模块111、红外线位置检测模块112和数据处理模块113，
该网络设置模块111用于将该红外设备110与辅助设备通信连接，以通过该辅助设备辅助该红外设备110连接至该云服务器120，以便于该红外设备110和该云服务器120创建该会议；
该红外线位置检测模块112用于根据用户在该书写承载介质上操作书写物体遮挡住红外线的分布情况，确定该书写物体在该书写承载介质上的坐标信息，并将该坐标信息发送给该数据处理模块113；
该数据处理模块113用于将该坐标信息进行处理后获取综合数据，并将该综合数据发送至该云服务器120；
该云服务器120用于存储该综合数据，并将该综合数据发送至该终端，以便于该终端根据该综合数据再现该书写承载介质上的书写内容。
因此，本发明实施例提供的多用户会议系统，通过用户在会议中书写时，书写物体对红外设备的红外线分布情况的影响，确定书写物体的坐标信息，将坐标信息处理后的综合数据发送至云服务器，以便于参与会议的终端根据综合数据再现会议中的书写内容，可以基于非图像数据传输会议内容，节省会议产生的数据流量，并能提高数据处理速度。
具体而言，本发明实施例的红外设备110是不具有显示屏的，使用时将其置于书写承载介质上，来获取书写承载介质上的书写坐标。书写承载介质可以是用于书写的白板、黑板、玻璃板或纸张等等。用于在书写承载介质上书写的书写物体可以是mark笔、钢笔、圆珠笔、铅笔、粉笔、橡皮、黑板擦、白板擦甚至手指等各种可用于书写出轨迹的工具，本发明实施例对书写 承载介质和书写物体的具体形式不作限定。本发明实施例的红外设备不具有显示屏，而是使用传统的书写承载介质和书写工具，一方面可以降低会议系统的成本，另一方面也更贴近人的使用习惯，提高用户体验。
网络设置模块111用于设置多用户会议系统100的联网参数。网络设置模块111可以通过蓝牙技术、红外技术或USB等数据通道连接辅助设备，通过辅助设备输入红外设备110的网络配置参数，连接指定的云服务器120。红外设备110第一次连接云服务器120时，可以将相应的网络配置参数保存在红外设备110的本地存储模块(图1中未示出)中。再次开启使用红外设备110时，红外设备110可以根据本地存储模块中存储的网络配置参数，自动与云服务器120连接，本发明实施例对此不作限定。红外设备110和云服务器120连接后，可以创建会议并传输会议内容。
应理解，本发明实施例中的辅助设备可以是参与会议的用户使用的终端，也可以是其它的辅助输入的设备，本发明实施例对此不作限定。数据处理模块113可以对从红外线位置检测模块112接收到的坐标信息，进行记录，保存，分析，计算等处理，例如对收到的坐标信息进行插值平滑处理，以平滑书写内容的线条。当然，数据处理模块所做的处理全部或部分工作，也可以由终端或终端上的客户端来执行，本发明实施例对此不作限定。
红外线位置检测模块112用于根据用户在会议中操作书写物体遮挡住红外线的分布情况，确定书写物体的坐标信息。具体地，红外线位置检测模块112可以是红外线发射单元、红外线接收单元和相应电子处理单元。红外线位置检测模块112可以是尺寸固定的闭合的红外边框，也可以是可以根据用户需要的尺寸自由组装成红外边框的多个红外线发射阵列和多个红外线接收阵列，还可以是其它形式的红外线位置检测模块或红外边框，本发明实施例对此不作限定。
应理解，红外线位置检测模块112确定在不同时刻书写物体的坐标信息，该坐标信息还可以包括书写物体的尺寸大小。书写物体的尺寸大小可以对应其在系统中的软件作用，生成坐标数据的功能属性信息。该功能属性信息可以包括书写/擦除、内容颜色、笔迹粗细等信息，本发明实施例对此不作限定。
红外线位置检测模块112将坐标信息对应的原始数据发送给数据处理模块113。数据处理模块113将该坐标信息进行处理后获取综合数据，并将综合数据发送至云服务器120。数据处理模块113对数据进行记录、识别、融 合和传输。
其中，数据处理模块113记录红外线位置检测模块112检测到的坐标信息(包括位置坐标数据和大小数据等)。数据处理模块113还可以根据红外线位置检测模块112搜集来的书写物体的大小，识别书写物体，并根据书写物体在现实中的实际作用确定其在系统中的软件作用，生成功能属性信息。该功能属性信息可以包括书写/擦除、内容颜色、笔迹粗细等信息。当然，该功能属性信息还可以通过外部传感器或功能按钮来确定，本发明实施例对此不作限定。数据处理模块113还可以用于将上述坐标信息、功能属性信息和坐标信息对应的时间信息、红外设备的物理标识(物理ID)以系统指定的数据格式融合。此外，数据处理模块113还可以融合其它信息搜集模块(图1中未示出)搜集的一些其它信息。其中，其它信息模块可以是音频拾取模块或视频拾取模块等，本发明实施例对此不作限定。数据处理模块113将经过上述处理后的综合数据存储在所述本地存储模块中，并可将综合数据发送至云服务器120。
应理解，该数据处理模块113可以通过WLAN网络或移动通信网络与该云服务器120进行通信。即，红外设备110与云服务器120通信可以是通过Wi-Fi，也可以通过移动通信网络，但本发明实施例并不仅限于此。
图2示出了本发明实施例的多用户会议系统的应用示意图。如图2所示，可将边框状的红外设备110置于书写承载介质130(例如白板等)上，利用辅助设备150(例如手机等)，将红外设备110与云服务器120通信连接。红外设备110将获取的用户在书写承载介质130上操作书写物体生成的坐标信息发送给云服务器120。云服务器120实时记录并存储红外设备110中的数据处理模块113生成的综合数据。云服务器120与参与会议的多个终端140相关联，云服务器120将当前的多用户会议系统100中的综合数据发送到指定终端140。终端140可以通过终端140上特定的软件，例如微信、邮件或应用客户端APP等接收会议内容。多个终端140通过特定的软件，绑定指定多用户会议系统的云服务器120，接收并解析综合数据成为坐标信息、尺寸大小信息等，还原功能属性信息，并按坐标信息对应的时间信息再现会议的书写过程。
可选地，在本发明实施例中，该网络设置模块111基于蓝牙技术、红外技术或wifi网络，将该红外设备110与该辅助设备通信连接，通过该辅助设 备上的应用客户端提供的设置页面进行设置，以使得该红外设备110连接至该云服务器120或更改该红外设备110的网络设置。
具体而言，由于本发明实施例的红外设备110不具有显示屏，因此可以配合如图2所示的辅助设备150，通过该辅助设备150上的应用客户端提供的设置页面，设置红外设备110的网络设置，使红外设备110连接至该云服务器120。后续还可以通过辅助设备150更改该红外设备110的网络设置。其中，网络设置模块111可以基于蓝牙技术、红外技术或wifi网络，将该红外设备110与该辅助设备150通信连接。此外，还可以通过USB运行相应的程序为红外设备110进行网络设置，本发明实施例对此不作限定。
可选地，在本发明实施例中，该红外设备110还可以包括本地存储模块，该本地存储模块用于实时记录并存储当前该书写承载介质上对应的该综合数据。
具体而言，由于本发明实施例的红外设备110不具有显示屏，为了方便用户管理会议，可以在红外设备110中设置本地存储模块，以实时记录并存储当前书写承载介质的一页对应的综合数据。由此，当发生突然断电或其它突发情况时，可以对本地存储模块中存储的数据进行处理，以恢复正常的会议数据。该数据处理模块具体可以用于在该书写承载介质的一页书写完成时，将该本地存储模块存储的该书写承载介质的一页对应的该综合数据发送至该云服务器。每当书写承载介质的一页书写完成时，数据处理模块可以将本地存储模块中存储的该页的综合数据进行处理，生成该页的会议文件，发送给云服务器120。
可选地，在本发明实施例中，在该红外线位置检测模块的电源关闭时，该数据处理模块113将该本地存储模块存储的该综合数据发送至该云服务器120，并且该本地存储模块存储的该综合数据不清空。
具体而言，通常而言，设备断电时，设备的内存做清空处理。而本发明实施例中，当红外线位置检测模块112的电源关闭时，即红外线位置检测模块112断电时，数据处理模块113将本地存储模块存储的综合数据(断电当时书写承载介质上内容对应的数据)发送至云服务器120。同时，本地存储模块存储的综合数据不进行清空，而是等待红外线位置检测模块112重新上电后继续处理。由此，可以保证突然断电时，书写内容不丢失。
可选地，在本发明实施例中，该数据处理模块113还用于检测当前获取 的坐标是否与该本地存储模块内存储的综合数据中的坐标重合，在该当前获取的坐标与该本地存储模块中存储的综合数据中的坐标重合时，该数据处理模块113将本地存储模块中存储的综合数据发送至该云服务器120，并删除该本地存储模块中已发送至该云服务器120的综合数据。
具体而言，在红外线位置检测模块112断电后又上电时，数据处理模块113用于检测当前红外线位置检测模块112获取的坐标是否与该本地存储模块内存储的综合数据中的坐标重合。如果重合，则说明断电期间书写承载介质的内容可能被擦除了，此时，数据处理模块113将本地存储模块中存储的综合数据发送至该云服务器120，并删除本地存储模块中已发送至云服务器120的综合数据，即将新书写的内容认为是新的一页书写内容。换而言之，当数据处理模块113发现目前的书写是在已有书写内容的区域开始一定规则的书写，导致内容重合时，将之前存储在本地存储模块中的数据存储到云服务器120，清空本地存储模块中的数据，将新的内容作为新建的一页进行存储。因此，上述实施例考虑设备电源的开关对数据存储的影响，保证电源开关时书写内容的完整性。
应理解，本发明实施例中，数据处理模块113将本地存储模块中存储的综合数据发送至该云服务器120可以是实时发送并由云服务器120实时存储的，也可以是本地存储模块存储书写承载介质一页的综合数据后，再向云服务器120发送并由云服务器120存储的。不同的发送存储方式使得数据处理模块113和云服务器120的处理过程不同，本发明实施例对此不进行赘述。
可选地，在本发明实施例中，该综合数据中包括用于指示该红外设备100的物理标识，该云服务器120根据该物理标识，为该红外设备110分配对应的存储空间，并将该综合数据存储在该存储空间中。
具体而言，当数据处理模块113检测并接收到红外线位置检测模块112生成的坐标信息时，将坐标信息和指示该红外设备110的物理标识进行融合，形成综合数据。数据处理模块113马上连接并将综合数据发送至云服务器120。云服务器120在接收到综合数据时，首先从中提取红外设备110唯一对应的物理标识(物理ID)，并为红外设备110分配唯一对应的存储空间。
可选地，在本发明实施例中，该多用户会议系统100为该会议分配会议标识，该终端通过应用客户端输入该会议标识接入该会议。
具体而言，多用户会议系统100为该会议分配会议标识，以使得终端通 过应用客户端输入该会议标识接入该会议。应理解，会议标识可以用红外设备110(例如数据处理模块113)生成，也可以由云服务器120在接收到会议内容中的坐标信息后对应生成，本发明实施例对此不作限定。终端通过输入会议标识(会议ID)或会议ID和对应的会议接入密码与会议ID绑定，以实现云服务器120向加入会议的终端发送会议内容。此外，本发明实施例中，终端也可以通过扫描红外设备110的唯一的物理ID，将终端与红外设备110绑定，从而进一步实现与会议绑定的目的。
通过上述行为，使用终端的用户要获取会议内容，需要通过安全认证过程，即仅允许安全用户访问云服务器120存储的书写内容。终端可以直接进行安全设置，也可以结合其它工具进行安全设置，例如微信、摇一摇等，从而提高安全性。云服务器120可以向终端提供丰富的分享模式，例如实时会议、会议文件、邮件等等，本发明实施例对此不作限定。
应理解，终端扫描红外设备110可以通过二维码、条形码或蓝牙等，本发明实施例对此不作限定。还应理解，本发明实施例中的终端与会议绑定，终端与红外设备110绑定，可以是以ID的形式对应，例如形成表来形成对应关系，但本发明实施例并不仅限于此。
应理解，数据处理模块113可以将坐标信息和坐标信息对应的时间信息以系统指定的数据格式融合，形成综合数据。坐标信息对应的时间信息可以通过计时器生成，也可以通过其它的计时设备生成，本发明实施例对此不作限定。
相应地，可选地，在本发明实施例中，该综合数据包括该红外线位置检测模块111按时间顺序获取的坐标信息，以便于该终端根据该按时间顺序获取的坐标信息再现书写的过程。可选地，在本发明实施例中，该综合数据包括该坐标信息和与该坐标信息对应的时间信息，以便于该终端根据该时间信息和该坐标信息再现书写的过程。终端接收并云服务器120发送的坐标信息和时间信息，根据该坐标信息和时间信息，对会议中的书写内容执行快进操作、后退操作或从特定时刻再现。
换而言之，时间信息可以以隐式的方式指示，也可以以显示的方式指示。对于隐式指示，例如以5ms为间隔，坐标信息占据n个比特，则第一个n比特表示第一个5ms的坐标信息，第二个n比特标识第二个5ms的坐标信息，……依此类推。这种方式要求在用户没有书写任何内容的空窗期时，以 特定值填充坐标信息。
对于显式指示，数据处理模块113可以在综合数据中，增加与坐标信息对应的时间信息。例如，可以使用具体时刻值，也可以使用序号(每两个序号之间的间隔是预定义好的)外加初始时刻值的方式，但本发明实施例并不仅限于此。本发明实施例中加入时间信息，可以使整个书写过程更完整地再现，给用户更好的体验，而不是传统的那样仅仅再现书写的最终结果。
可选地，在本发明实施例中，该红外设备110还用于外接音频设备，以便于通过该音频设备输入或输出音频数据。或者，可选地，该红外设备110还包括音频模块，以便于通过该音频模块输入或输出音频数据。
具体而言，如图3所示，上述音频设备或音频模块可以包括麦克风160和/或扬声器170。麦克风160可以实现会议中将进行书写的用户的语音输入。扬声器170可以帮助终端的客户端对书写的用户的语音实现反馈。应理解，该反馈可以是实时反馈，也可以是延后反馈，延后反馈时其功能类似于留言机功能。此外，扬声器170还可以用于为会议播放背景音乐。该音频设备或音频模块使得再现的会议内容更丰富，扬声器则更是可以实现会议反馈能力，可以增强用户的体验。
应理解，本发明实施例的音频设备或音频模块，例如麦克风160和/或扬声器170还可以内置在红外设备110中，也可以通过线路、WLAN、蓝牙技术或红外技术与该红外设备110连接。麦克风160采集的数据可以融合入综合数据，发送给云服务器120，并传输至参与会议的终端。
可选地，在本发明实施例中，该红外设备110还用于外接本地再现设备，该数据处理模块113还用于将该综合数据发送给该本地再现设备，以便于该本地再现设备根据该综合数据在本地进行再现该会议的内容。
具体而言，如图3所示，红外设备110还可以外接本地再现设备，例如图3中的显示器180和打印机190等。红外设备110通过数据处理模块113将会议产生的综合数据发送给该本地再现设备。该本地再现设备根据该综合数据在本地再现该会议的内容，可以进一步增强用户的体验。例如，通过显示器180在本地显示会议的内容，或由相应的程序控制打印机，通过打印机将会议内容打印出来等。此外，本地再现设备还可以对再现的内容进行渲染，如场景模拟、现实增强等，以增强会议效果。可选地，该本地再现设备可以为显示设备或打印设备，但本发明实施例并不仅限于此。应理解，该本地再 现设备可以通过线路、WLAN、蓝牙技术或红外技术与该红外设备110连接。
可选地，在本发明实施例中，除将本地再现设备与红外设备110连接，接收红外设备110数据的方案以外，本地再现设备的数据也可以来自于云服务器120。相应地，该云服务器120还用于与本地再现设备通信连接，该云服务器120将该综合数据发送给该本地再现设备，以便于该本地再现设备根据该综合数据在本地再现该会议的内容。
在具体的实现中，用户可以通过红外设备110上的按钮等硬件或者通过微信、APP等软件发出本地再现指示。如果本地再现指示是通过红外设备110上的按钮等硬件发出的，则由红外设备110向该云服务器120发送指示信息，指示云服务器120将该综合数据发送给该本地再现设备；如果本地再现指示是通过软件发出的，则该指示可以发送给红外设备110，由红外设备110向该云服务器120发送指示信息，也可以是直接发送给云服务器的。应理解，在本发明实施例中，本地再现设备的数据也可以来自于云服务器120，需要将本地再现设备在云服务器120处或红外设备110处进行注册或绑定，其注册或绑定的方式与红外设备110、云服务器120、用户使用的终端的绑定可以相类似，本文中不再进行赘述。
因此，本发明实施例提供的多用户会议系统，通过用户在会议中书写时，书写物体对红外设备的红外线分布情况的影响，确定书写物体的坐标信息，将坐标信息处理后的综合数据发送至云服务器，以便于参与会议的终端根据综合数据再现会议中的书写内容，可以基于非图像数据传输会议内容，能够实现会议内容的远程推送，并可以节省流量，降低会议系统对网络流量的要求。另外，相比于现有的拍摄或视频模式，本发明实施例的方案更节省流量，并且再现效率高，即在相同数据流量的情况下，本实施例的方案的采样频率高得多。
由于当前有越来越多的场景为多个公司或多人在同一个场地办公，这就有可能会出现多个公司或多人使用或租用同一个多用户会议系统来开展会议。并且，上述多用户会议系统产生的会议数据是非图像的数据，是基于会议中书写的内容形成的重要数据，因此，需要保证会议中产生的数据的安全性，避免数据被非参与会议的人获取。
图4示出了根据本发明实施例的多用户会议系统200的示意性框图。如图4所示，多用户会议系统200包括位置检测传感器210、数据处理模块220 和云服务器230，其中，该数据处理模块220分别与该位置检测传感器210和该云服务器230通信，该位置检测传感器210用于获取用户在书写承载介质250上进行书写时产生的位置信息，所述数据处理模块220用于对所述位置信息进行处理以便于所述多用户会议系统200生成会议数据，
该云服务器230用于接收第一终端240发送的会议发起请求，该会议发起请求用于指示该第一终端240请求使用该位置检测传感器210发起第一会议，向该第一终端240发送使用鉴权指令，该使用鉴权指令用于指示该第一终端240的用户通过该位置检测传感器210进行使用确认；
该位置检测传感器210还用于获取用户输入的输入信号；
该数据处理模块220还用于从该位置检测传感器210获取该输入信号，根据该输入信号生成并向该云服务器230发送使用确认信号，该使用确认信号中包括用于指示该位置检测传感器210的标识；
该云服务器230还用于在接收到该位置检测传感器210发送的该使用确认信号，确认该第一终端240的用户具有使用该位置检测传感器210的权限时，向该第一终端240发送该第一会议的会议标识，以便于该第一终端240向第二终端传输250该会议标识；
该云服务器230还用于接收该第二终端250发送的包含该会议标识的会议接入请求，允许该第二终端250接入该第一会议，并向该第二终端250发送该第一会议的会议数据。
本发明实施例的多用户会议系统指示发起会议的用户在位置检测传感器上做出相应的操作，从而确认用户具有使用位置检测传感器的权限，使得不在位置检测传感器旁边的人，因为无法完成系统指示的操作而不能发起会议，从而保证了会议的安全性。
在本发明实施例中，位置检测传感器210和书写承载介质260可以是合一设置的，例如通常所见的电容式触摸屏或电阻式触摸屏。
在本发明实施例中，位置检测传感器210和书写承载介质260也可以是分离设置的。例如，书写承载介质可以为用于书写的白板、黑板、玻璃板或纸张等等。用于在书写承载介质上书写的书写物体可以是mark笔、钢笔、圆珠笔、铅笔、粉笔、橡皮、黑板擦、白板擦甚至手指等各种可用于书写出轨迹的工具，本发明实施例对书写承载介质和书写物体的具体形式不作限定。使用时位置检测传感器210置于书写承载介质260上，当用户用书写物体在 书写承载介质260上书写时，位置检测传感器210获取书写时产生的位置信息。
位置检测传感器210可以是基于光学技术(例如通过摄像头捕捉书写物体的位置信息)的位置检测传感器；位置检测传感器210也可以是基于超声波技术的位置检测传感器；优选地，位置检测传感器210还可以是基于红外线技术的位置检测传感器，基于红外线技术的位置检测传感器可以不具有显示屏。
应理解，本发明实施例的多用户会议系统200中的位置检测传感器210的功能可以与多用户会议系统100中的红外设备110的红外位置检测模块112的功能相对应。
红外设备110的网络设置模块111和/或数据处理模块113可以与位置检测传感器210部署在一起(即网络设置模块111和/或数据处理模块113与位置检测传感器210可以是合一设置的)，也可以单独部署(即分别单独设置)，数据处理模块113可以与多用户会议系统200中的云服务器230部署在一起(即数据处理模块还可以部署在云服务器中)。
换而言之，本发明实施例的位置检测传感器210和云服务器230，以及其他的功能模块可以以各种可能的方式进行部署，以用于实现本发明实施例中谈到的多用户会议系统100和多用户会议系统200的各种功能，本发明实施例对此不作限定。
应理解，本发明实施例中的位置检测传感器和书写承载介质的组合可以形象的称作“数字白板”。
下面结合图5从发起会议的整个流程，介绍本发明实施例的方法300和多用户会议系统。
S301，想要发起会议的用户在多用户会议系统30中的第一终端34上通过应用客户端(Application，APP)或微信服务号向云服务器33发送会议发起请求。该会议发起请求用于指示第一终端34请求使用位置检测传感器31发起第一会议。相应地，云服务器33接收第一终端34发送的会议发起请求。
具体地，用户可以通过扫描二维码生成并发送该会议发起请求。扫描二维码需使用特定的APP或微信服务号的相应功能。APP或微信服务号的相应功能应是预先编程的，使得会议发起请求发送的目的地址为云服务器33。 其中，二维码的内容可以为位置检测传感器31的标识(此标识可以为物理标识，例如设备号等)，该标识为唯一的标识。
除了通过扫描二维码的方式发起会议外，还可以通过其他方式发起会议。例如，用户可以通过APP或微信服务号的浏览界面输入位置检测传感器31的标识，输入的标识可以是一串字符串(例如，可以是一串数字或者字母与数字的组合)。由浏览界面生成包含位置检测传感器31的标识的会议发起请求，并将会议发起请求发送至云服务器33。
S302，云服务器33向该第一终端34发送使用鉴权指令，该使用鉴权指令用于指示该第一终端34的用户通过该位置检测传感器31进行使用确认。该使用鉴权指令可以通过第一终端34显示给用户。
在一个具体的例子中，使用鉴权指令的具体内容可以是“您确定要发起一个新会议吗？如果是，请点击本界面的确认按钮，并请按下位置检测传感器上的使用确认按钮；如果否，请点击本界面的取消按钮”。
或者，在另一个具体的例子中，使用鉴权指令的具体内容可以是“您确定要发起一个新会议吗？如果是，请点击本界面的确认按钮，并请在书写承载介质上的鉴权功能区域(预设的功能区域)内点击或进行任意书写；如果否，请点击本界面的取消按钮”。
或者，在又一个具体的例子中，使用鉴权指令的具体内容可以是“您确定要发起一个新会议吗？如果是，请点击本界面的确认按钮，并请在书写承载介质上的书写一个圆圈(预设的轨迹)；如果否，请点击本界面的取消按钮”。
或者，在又一个具体的例子中，使用鉴权指令的具体内容可以是“您确定要发起一个新会议吗？如果是，请在书写承载介质的键盘功能区域内输入验证字符串“1234”；如果否，请点击本界面的取消按钮”。
S303，第一终端34的用户，即发起会议的用户根据鉴权指令，在位置检测传感器31上操作，位置检测传感器31获取用户输入的输入信号。
S304，该数据处理模块32从该位置检测传感器31获取该输入信号，根据该输入信号生成并向该云服务器33发送使用确认信号，该使用确认信号中包括用于指示该位置检测传感器31的标识；
对于S303和S304，具体地，用户可以通过按下位置检测传感器31上的按钮(物理按钮)形成的信号，将该按下按钮形成的信号作为该输入信号， 位置检测传感器31获取该输入信号。数据处理模块32从该位置检测传感器31获取该输入信号，对该输入信号进行辨识，发现其为按下相应按钮形成的信号时，对该信号进行处理，并增加位置检测传感器31的标识信息，形成云服务器33可以识别的使用确认信号。
用户也可以通过在书写承载介质上进行书写，以进行使用确认。位置检测传感器31获取用户在所述书写承载介质上进行书写所产生的位置信息形成的信号，将所述书写所产生的位置信息形成的信号作为所述输入信号。其中，在所述书写承载介质上进行何种书写所产生的位置信息是用来进行使用确认的，可以由系统进行预定义，也可以由用户进行预设置。数据处理模块32从该位置检测传感器31获取该输入信号，对该输入信号进行辨识，发现其符合预定义或预设置时，对该信号进行处理，并增加位置检测传感器31的标识信息，形成云服务器33可以识别的使用确认信号。
该输入信号可以为用户在书写承载介质上以预设的轨迹进行书写所产生的位置信息形成的信号。预设的轨迹可以是画出特殊的形状，例如，三角形、圆形、方形等等；预设的轨迹可以是也可以是书写特殊的字符，例如，use，U等等，本发明实施例对此不作限定。
该输入信号为用户在所述书写承载介质上预设的功能区域内进行书写所产生的位置信息形成的信号，例如，可以是点击一下功能区域或在功能区域内进行任意书写，也可以是更复杂的输入方式。例如，该功能区域为一个键盘功能区域，键盘功能区域可以是类似数字键盘形式的一个虚拟的区域，或者类似包括字母和/或符号的标准键盘形式的一个虚拟的区域。用户根据使用鉴权指令中指示的验证字符串(例如，验证字符串“1234”)，在键盘功能区域内进行输入(该输入可以是点击键盘上的相应数字、字母或符号)，形成输入信号。数据处理模块32获取该输入信号，对该输入信号中的位置信息进行辨识，确定出用户输入的验证字符串，对该验证字符串进行处理，并增加位置检测传感器31的标识信息，形成使用确认信号，进一步还可以对使用确认信号进行加密，而后发送给云服务器33。
本发明的用户通过在书写承载介质上进行书写以产生输入信号，并有输入信号生成使用确认信号的几个实施例设计不同的方式来产生并传输使用确认信号，输入具有一定的复杂度，可以达到更好的鉴权效果。
用户还可以通过第一终端34中的近场通信(Near Field Communication， NFC)技术向位置检测传感器31发送输入信号。这要求第一终端34和位置检测传感器31均具有NFC功能。具体而言，第一终端34和位置检测传感器31可以使用NFC功能的点对点模式(P2P mode)，该点对点模式与红外线和蓝牙的功能类似。NFC功能的传输距离较短，传输创建速度较快，传输速度较快，并且功耗低，两个具备NFC功能的设备连接可用于数据交换。在本发明实施例中，用户可以操作第一终端34生成输入信号，通过NFC功能向位置检测传感器31发送该输入信号。
此外，用户还可以通过在位置检测传感器31上刷员工(Identification，ID)卡，识别员工的身份。这样要求位置检测传感器31具备读取集成电路(Integrated Circuit，IC)卡的功能，本发明实施例对此不作限定。
数据处理模块32生成使用确认信号后，向云服务器33发送该使用确认信号。
S305，云服务器33在接收到该数据处理模块32发送的该使用确认信号时，确认该第一终端34的用户具有使用该位置检测传感器31的权限。具体而言，云服务器33对使用确认信号进行验证后，例如比较使用确认信号与预设的信号或理论上正确的信号进行比较后，确认用户具有使用该位置检测传感器31的权限。验证信号的具体方法可以基于使用确认信号中包括的位置信息等进行验证，此处不进行赘述。
应理解，云服务器33可以预设一个第一时间段(例如5分钟)，用户只有在第一时间段内触发位置检测传感器31，并向云服务器33发送使用确认信号时，才是有效的使用确认；如果超出第一时间段，则认为是使用确认失败，即认为第一终端34的用户不具有使用该位置检测传感器31的权限。在这种情况下，用户如果想再次发起会议，可以重复执行S301至S303。
具体而言，S303至S305的思想为，使用位置检测传感器31的唯一的标识(或称为设备码)和会议发起人按照云服务器33的指示在位置检测传感器31上做出相应的操作，共同组成鉴权的过程。在上述两者都具备时，确认第一终端34的用户具有使用该位置检测传感器31的权限。这样使得不在位置检测传感器31旁边的人，因为无法完成云服务器33指示的操作而不能发起会议，从而保证了会议的安全性。
S306，云服务器33向该第一终端34发送该第一会议的会议标识。
具体而言，经过S301至S305，云服务器33认为第一终端34的用户具 有使用该位置检测传感器31的权限，即云服务器33通过用户的会议发起请求，允许用户发起一个会议。优选地，用于指示该第一终端34请求使用该位置检测传感器31发起第一会议的会议发起请求中可以包括用于指示该位置检测传感器31的标识的信息。该云服务器33根据该标识，为该位置检测传感器31分配对应的存储空间，以便于将该第一会议的会议数据存储在该存储空间中。同时，云服务器32为第一会议生成一个会议标识(会议ID)，并将该会议标识通知给第一终端34。
S307，发起会议的用户将会议标识通知给参与会议的至少一个其它用户。参与会议的其它用户包括在会议现场(即位置检测传感器31所在地)的用户和/或远程的用户。通知会议标识多种多样，例如可以通过电话、邮件、短信、微信等多种手段，本发明实施例对此不作限定。可选地，发起会议的用户可以通过第一终端34将会议标识发送给参与会议的其它用户使用的第二终端35。应理解，第二终端35可以为一个或多个终端，本发明实施例对此不作限定。
S308，参与会议的其它用户可以在第二终端35上输入会议标识或会议ID和对应的会议接入密码。通过第二终端35向云服务器33发送包含该会议标识的会议接入请求。
S309，云服务器33接收该第二终端35发送的会议接入请求。根据会议接入请求中包含的该会议标识，确定允许该第二终端35接入该第一会议。
在一个实施例中，云服务器33向第一终端34发送的该会议发起请求中包括用于指示会议时长的信息，该云服务器33从接收到该使用确认信号开始经过该会议时长的时间范围内接收到该第二终端35发送的包含该会议标识的会议接入请求时，允许该第二终端35接入该第一会议；否则，不允许第二终端35接入该第一会议。
S310，会议开始后，云服务器33向第一终端34发送该第一会议的会议数据，并且云服务器33向第二终端35发送该第一会议的会议数据。
在一个实施例中，云服务器33向第一终端34发送的该会议发起请求中包括用于指示会议时长的信息，该云服务器33从接收到该使用确认信号开始经过该会议时长之后，停止向接入该第一会议的终端(包括第一终端34和第二终端35)发送该第一会议的会议数据。
应理解，会议时长可以是发起会议的用户在发起会议是通过APP或微 信服务号输入的，也可以是多用户会议系统默认的。本发明实施例对此不作限定。
在本发明实施例中，多用户会议系统还可以包括网络设置模块，该网络设置模块用于将该位置检测传感器与辅助设备通信连接，以通过该辅助设备辅助该位置检测传感器连接至该云服务器。
在本发明实施例中，该数据处理模块还用于将位置信息进行处理后形成该第一会议的会议数据。
具体而言，对于位置检测传感器为不具有显示屏的，基于红外线技术或超声波技术的传感器，其与云服务器建立通信连接，可以通过其它的辅助设备，例如手机和电脑等等。位置检测传感器获取用户在书写承载介质上进行书写时产生的位置信息后，可以通过数据处理模块将该位置信息进行处理后形成该第一会议的会议数据。
应理解，网络设置模块和/或数据处理模块可以与位置检测传感器集成在一起，也可以以程序的形式安装在用户使用的终端(例如电脑)中，位置检测传感器可以通过有线形式(例如，通用串行总线(Universal Serial Bus，USB)接口)与终端连接。数据处理模块还可以部署在云服务器中，由云服务器将位置信息处理成会议数据，本发明实施例对此不作限定。
优选地，该第一会议的会议数据包括该位置检测传感器按时间顺序获取的坐标信息，以便于参与该第一会议的终端根据该按时间顺序获取的坐标信息再现书写的过程。在本发明实施例中，该会议数据可以包括位置信息和与该位置信息对应的时间信息，以便于该终端根据该时间信息和该位置信息再现书写的过程。终端根据该坐标信息和时间信息，可以对会议中的书写内容执行快进操作、后退操作或从特定时刻再现会议等等，从而可以提高用户的体验度。
